Table 4.

The conditions in Experiment 4 in which Frequency of trials and duration Adjusted for frequency of trials were manipulated.

		Duration (ms)
		300	1200	4800	300	1200	4800
Frequency	4		Few A	Few A Adj		Few B	Few B Adj
	16		Baseline			Baseline
	64	Many A Adj	Many A		Many B Adj	Many B
	4		Few C	Few C Adj
	16		Baseline
	64	Many C Adj	Many C

Note: Baseline was a single control condition analogous to Baseline in Experiments 1, 2, and 3, and was used to compare across the manipulations of the three types of trials (A, B, and C). In the Baseline condition, each trial type, A, B, C, and D, was repeated 16 times for 1200 ms. In the other conditions, Frequency or duration Adjusted for frequency of one type of trial (A, B, or C) deviated from the Baseline condition.
